There are free open source rating programs. Remi Coulom's version: http://remi.coulom.free.fr/Bayesian-Elo/ The Glicko system used by FICS: http://www.unix-ag.uni-kl.de/~chess/gicshelp/node177.html has source available here: http://sourceforge.net/projects/chessd There is the USCF formula, which I have made a public domain version here: http://cap.connx.com/tournament_software/USCF.C >The program that the israeli chess organization is using have a lot of >disadvantages. > >1)There is no option to calculate rating dynamically.

There are some programs here that might be helpful: http://cap.connx.com/tournament_software/ As you have probably noticed, my help on projects is spotty, because I run from project to project that looks interesting to me but I can perhaps be of some assistance from time to time.
